  • John listed and sold my home

      est realtor ever! My husband and I have bought homes with 7 realtors over many years. John is by far the best realtor we have ever worked with. John is responsive, a fabulous listener, patient, hard working and steady. We trust him completely! He is extremely knowledgable about the process, understands the market and has the most likable personality. Additionally, John has a good eye for design and architecture. When my husband and I decided to move back cross country to Philadelphia , John helped us find what we were looking for in a very competitive market. It took us almost 2 years to find our new home and 8 months of negotiation. John was able to overcome continuous obstacles with creative solutions. He didn't waste our time and only showed us the type of properties that matched what we were looking for. I love that he wasn't afraid to tell us if he thought a house or neighborhood was not a good match. He is extremely organized and punctual. John works well under pressure and goes the extra step to get the deal done, even if in reality it is the other realtor's responsibility! We also used John to sell our Philadelphia condominium, which sold at a premium and above our expectations on the first day of listing! He represents the seller with the same professionalism as he does the buyer. John is a pleasure to work with!

    • "For the first time in a long history of buying and selling properties, I can truly say I had a superb experience, 10 out of 10. John was trustworthy, patient, persistent, on top of things, and delivered excellent service. He, in my estimation, is a pro at what he does. Without hesitancy, I would recommend John, whether you are buying or selling."

    • "If you're looking to purchase in Philadelphia or the Main Line - I just finished working with John Duffy. John was incredibly genuine, easy to work with, never in a rush and available. He explained each step of the process as I searched for houses (including pointing out not only the positives of each home, but also the negatives and "things to think about regarding re-sale"). It was obvious that he takes pride in his family business. If you're a physician, he also worked closely with my bank for a physician loan (so he is well-versed in what's available specifically for physicians). Highly recommended."

      - Chris P.
    • "I recommend John to every buyer or seller I come in contact with since I have never met anyone with his level or skill, integrity, or patience with our extensive search. John Duffy Jr. is a credit to this profession and will help you find the property of your dreams. The best experience of my life!."
